Abstract

Background:  Heart rate variability (HRV) and decre-ased Quality of Life (QOL) are among the major risk factors for deaths due to cardiac complication in Pakis-tan after angioplasty. In the past, various studies have been conducted on animals to investigate the influence of exercise programs. Plenty of evidences have been available which suggest the importance of such phy-sical training programs to increase HRV and reduced mortality after catherizations in human populations as well. In our recent studies, we have appraised the cha-nge in exercise capacity, quality of life and HRV in cardiac rehabilitation patients by randomising them between either conventional or intensive physiothe-rapy follow up programs in Pakistan. In our current prospective study design, stratified randomization was adopted and pre-specific subgroup analysis was also performed.

Methods:  We used exercise tolerance test and Adop-ted Quality of Life Questionnaire at baseline, 4 and 12 months after myocardial infarction (MI) or Angio-plasty. Sixty two patients including 43 with MI and 19 with Angioplasty were randomised with double blind randomization. Study subjects were randomly alloca-ted to either twice weekly (N) or six times weekly (I) physiotherapy follow up programs at a physiotherapy outpatient department.

Results:  Exercise capacity, Global HRV measure-ments and quality of life were improved significantly in group (I) after 3 months physiotherapy follow up and these results were consistently better than group (N) even after one year. A momentous HRV response was seen in angioplasty patients as compared to MI patients when a subgroup analysis was performed at 3 months after intensive physiotherapy follow up.

Conclusion:  Intensive physiotherapy follow up progr-ams in cardiac rehabilitation increases exercise capaci-ty, quality of life and global HRV measurements thus reducing the number of deaths due to cardiac compli-cations. These results could have important prognostic significance among cardiac patients in Pakistan.
